SET-wo RKS FOR sAw-M I Ls.
SPECIFICATION forming-...part ofLetterslIPatent`No.`282,214, dated July 31, 1883.
4 Application `filed May 1, 1883.` (No model.)
To LZZ whom zit may,cancel/'12,: s Be it knownthat I, ALEXANDER (LOsBoRN, of Clarksburg, `Harrison county, andState of West Virginia, have invented a new and useful Improvement in: Set-Works for` Saw-Mill Head-Blocks, of which'the following is a full, clear, and exact description, Myinvention'relat'es to the mechanism `for operating and adjusting the set-works of sawmill head-blocks, and it consists, first, in adevice for regulating the throw of the hand-lever by which the ratchet-wheels are operated to move the log; and, second, in a rack-and- `pinion device'for turning the pawl of the describedand claimed.
Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicate corresponding parts in all thefigures.- l
Figure 1 is a side view, partially sectional, of a saw-mill head-block with my improvements applied to `theset-works. Fig.`2 is a plan view of the same, and Fig. 3 is a trans- A verse section on line so x of Fig. 1.
A is the head-block. B is the shaft of the set-works. C C are the ratchet-wheels keyed on the shaft, and D is the hand-lever loose on the shaft, and carrying pawls E E for engaging the ratchet-wheels. the usual construction, as will be also the `devices operated by the shaft, which are notv shown.
The lever D is @Xtened below the shaft, and to its lower end is connected aA rod, F, that extends to a box, G, at the under side of block A, where the rod connects to a slide, H, which is fitted for movement lengthwiseof the box. In the upper and under sides of the box are holes afor receiving a pin, I, by which the movement of the slide is limited in one direction, the reverse movement being limited by theend of the box. The holes are as immerous as maybe required, so that the pin can be shifted to vary the length of movement allowed to the slide H and rod F, and` consequently `to `the lever D, thus regulating `the extent of movement given the ratchet-wheels by the lever, and the leverand the forward movement of the log. In this manner the thickness of lumber sawed is governed.
The operating-pawls E are hung on a spindie, b, on Athe lever D, there being also pinions K on the spindle.
These parts are of raised by means of a foot-lever, N, to which the pieces L are connected. To revolve the pawls the lever N is pressed down, which engages the racks withthe pinions K, andthe hand-lever being then moved, the pinions are turned by their engagement with the racks and the pawls swung over to either side for moving the ratchet-wheels in the direction desired. r
At the outer end of lever N is connected an arm, o, that extends up to the back pawls, P, and the hole for the pin connecting the lever to the piece L is elongated, so that by a slight movement by the lever the pawls l? can be raised without raising the piece L. This is done when -it is desired to work the ratchets backward. y
In place of using a rack and pinion, a friction-disk and curved arc may be used.
Having thus described my invention, I claim as new and desire to secure by Letters Patent* f l. The combination, with the hand-lever D, extended below the shaft B of the set-works, of the box G, having holes a, the pin I, working in any of said holes, the slide H, adapted .to move longitudinally in said box, and the rod F, connecting the lever with the slide, for the purpose specified.
2. 'Ihe combination `of slide H, having' a movement limited by movable pins I, and rod F, with head-block A and lever D, for operating the set-works, substantially'as described.
3. The combination, with the pawls E and pinions K, arrangedon the spindle b of the lever D, of the ratchet-wheels C, provided with a loosely-hungand vertically-movable top ratcheted piece, L, on each hub, and the `foot-lever N, connected with said pieces L, for the purpose specified.
4. Thefoot-lever N, connected by a pin and elongated slot with the piece L, and having ran end arm, o, extending to the back pawls, l),
as and for the purpose specified.
